Introduction

Exercise stress test is a common test that is currently available in most of the diagnostic centres all over the world. The main purpose of performing this stress test is to observe and determine how well the heart of an individual is functioning under stress. The test actually defines the response of the heart under stress, when it has to work its hardest. Individuals appearing for the exercise stress test are asked to run on a treadmill while the heart activities are monitored by healthcare professionals. However, the test may be stopped if any individual experiences any serious health complication during the process.

Why are stress tests performed?

Stress tests are mainly performed for understanding

  • How well the heart of an individual is pumping blood

  • How the individual performs compared to others of the same age

  • Whether the heart of that individual is receiving adequate blood supply or not

  • Whether the heart symptoms that have been occurring lately are coming back after putting the heart on stress or not.

What does the stress test help to understand?

The stress test helps to understand

  • Whether there are any underlying issues with the heart muscles or valves.

  • Whether the heart muscles are getting adequate blood supply or not.

  • How much the heart’s electrical stability is during exercise.

How is the exercise stress test performed?

  • At first, a technician will measure the heart rate and the blood pressure.

  • Then a certain number of electrodes will be attached with your arms and chest. The electrodes will stay connected to the EKG machine.

  • Then you will be asked to walk on a treadmill, or maybe to pedal a stationary bicycle at minimal speed.

  • After that, they may ask you to increase the pace.

  • The technicians as well as the other healthcare professionals will keep asking you about how you feel during the process.

  • After you maintain your targeted heart rate for as long as it takes to get the necessary readings, the test ends. It roughly takes 10-15 minutes.

The bottom line

It’s also important to know about how to prepare yourself for the test. You may be asked to restrict the consumption of caffeine and tobacco products for at least 24 hours before you appear for the test. Apart from that, you may also be asked to stop taking certain medications before appearing for the test. You may consult a genuine pathology lab like Orange Health Labs to gain more necessary information about the preparations that are needed to be taken before appearing for this test.
